Exam 14: Oscillations

A simple pendulum and a mass oscillating on an ideal spring both have period T in an elevator at rest. If the elevator now accelerates downward uniformly at 2 m/s², what is true about the periods of these two systems?

The period of a simple pendulum that is 1.00 m long on another planet is $1.66 \mathrm {~s}$ What is the acceleration due to gravity on this planet if the mass of the pendulum bob is 1.5 kg?

The position of an object that is oscillating on a spring is given by the equation x = (18.3 cm) cos[(2.35 s^-1)t]. What are the (a) frequency, (b) amplitude, and (c) period of this motion?

A simple pendulum and a mass oscillating on an ideal spring both have period T in an elevator at rest. If the elevator now moves downward at a uniform 2 m/s, what is true about the periods of these two systems?

An astronaut has landed on Planet N-40 and conducts an experiment to determine the acceleration due to gravity on that planet. She uses a simple pendulum that is 0.640 m long and measures that 10 complete oscillations 26.0 s. What is the acceleration of gravity on Planet N-40?
